In partnership with the California Energy Commission and the City of San Diego, CSE is engaged in a multiyear project aimed at testing, verifying and publicizing the integration of energy efficiency, solar photovoltaic systems and other demand side resources to convert three public libraries to zero net energy (ZNE) or near ZNE buildings.

Benefits of the SD ZN3 Project

Environmental

Maximizing building performance and integrating sustainable technologies at the three libraries will reduce overall energy consumption by 932,124 kWh and offset 531,766 pounds of CO2 equivalent annually. The application of IDSM technologies and participation in demand response programs will reduce utility requirements to meet demand with fossil fueled peaker plants.

Grid Reliability

The presence of onsite renewable energy generation coupled with IDSM technologies will allow for the libraries to reduce overall consumption on the grid and shift load when energy demand on the grid is at its highest. Participation in demand response programs will not only increase grid reliability through reduced power interruptions and black outs, but will also provide additional revenue streams for participating customers.

Public Health

All three libraries are designated “Cool Zones” in San Diego County’s effort to provide safe locations where older adults and others can keep cool during the hottest days of the year. Improving the efficiency of these locations will reduce community-wide energy consumption and increase the community’s resiliency against the power demands during extreme weather events.
